HEEL-RAND CUTTING AND COUNTING MACHINE.

SPECIFICATION forming part of Letters Patent No.` 726,467, dated April 28, 1903. Application filed March 21,1902.- Serial No. 99.34B. (No model.)

To all whom it may concern:

Beit known that I, CHARLES O. RYBERG, a citizen of the United States of America, residing at Brockton, in the county of Plymouth and State of Massachusetts, have in vented certain new and useful Improvements in Heel-Rand Cutting and Counting Ma-` through the machine will be automatically counted or registered.

In the manufacture of boot and shoe heels the ends of the rand project beyond the end of the heel, thus necessitating the cutting or clipping off of the same even with the end of chinery, but more generally by hand, the operator employing a common knife for the purpose, the heels being passed from the table on which the rand is cut to a box or barrel and afterward counted while packing. With my improved machine the heel after being placed upon the table is automatically engaged by and carried into such position by a traveling chain or conveyer, whereby the cutting mechanism may be brought into action and the heel after having the ends of the rands thereof severed may be carried for-I ward by the chain, and during the travel of the heel on the bed of the table it may operate mechanism-to actuate a counter or regis- `ter before the heel is nally discharged into the barrel or box ready forl shipment.. This is accomplished by novel mechanism, a prac tical embodiment of lwhich is shown in the accompanying illustration, forming a part of this specification, and in describing my invention in detail, reference will be had to the drawings herewith,and wherein like nu merals will be employed to designate like parts throughout the several views, in which- This is sometimesdone by ma' Fig. 3 is a like view on line y y, Fig. 1; and `Y Fig. 4 is atop plan view of the device.

In the accompanying drawings, illustrating a device capable 'of carrying out the objects of my invention, 1 indicates the table orvbed, which may be supported in any suitable manner, this table or bed being provided throughout its length about centrally thereof with a groove or runway 3 to receive the chain constituting a part of the conveying mechanism, and thus permitting said chain during its travel to lie below the upper face of the bed or table. The table is provided along one sideA with a guard-rail 4, and at the side opposite to the rail'4 carries the guard-rails 6 and 7, whichextend but partially the length of the table'orbed, the space between the ends of the rails 6 and 7 being occupied by the cutter, which serves also as a guard-rail.

To the under face of the bed 1 are secured depending shaft-hangers 8 9, the latter extending for a distance beyond the side of the bed. A shaft 10, having the gear-wheel 11 on its one end, is carried by these shaft-hangers and has a toothed wheel12 secured there- Securely bolted to the bed is a bracket 14, carrying an upwardly-extending arm 15, provided with bearings in which are received shafts. The lower of these shafts carries a friction-wheel 16 on its one end and a cogwheel 17 on its other end, the latter intermeshing with a like wheel 1S, carried by the upper shaft. The invention aiming to provide a machine having a continuous action, it is therefore necessary to provide a cutting mechanism which shall at all times be invariable, and to these ends rotary Vcutter. 19 is carried by the upper shaft and has its cute ting edge projecting sufficiently beneath the upper faces of the bed in order to effect a clean cut of the rand from-the heel.

The friction-wheel, it will be noted, is placed sufficiently below the rotary cutter to enable the rand to be frictionally grasped while the cutting operation is proceeding.

y The gears 17 andlS being all of the same size, their relative speed will therefore be equal, movementbeing communicated to the upper one by means ofa drive-Wheel 20, which is connected to any suitable actuating means. (Not shown.)

Motion is imparted to the gear-Wheel ll by means of a gear 2l, secured to the shaft carrying the drive-wheel. Mounted Within suitable brackets 22 23 at the ends of the bed of the machine are the toothed wheels 24 25, over which andI the toothed wheel 12 passes the conveyer-chain 26, carrying the conveyerblocks 27, having their engaging faces preferably curved to conform to that of the heel. This conveyer-chain extends within the runway 3 and is so positioned as to enable the conveyer-blocks to easily pass along the length ofthe bed, the blocks extending across this runway, will be noted. The adjustment of the tension ot' the chain is effected by slidably mounting one pair of the brackets and providing the same With lugs 28, in which operates a set-screw 29, carried by the stationary bracket 30, secured to the bed l. Any tendency of the heel to have a vertical movement during the cutting and counting operation is provided for by the employment of a iiat retention-spring 3l, extending a portion of the length of the bed and having its one end bowed upwardly and rigidly secured to a bar 32, extending in a direction transverse to that of the bed. Heels of varying thickness require that the position of the spring with relation to the bed be made to conform therewith in order to effect an easy passage of the heel along the table, which is overcome by enabling the bar carrying the spring to have a vertical adjustment. This latter is effected by providing the bar at its one end with a depending foot 33, carrying a set screw adapted for engagement with the recessed enlargement 34, carried by the bed, and at its other end with a vertical set-screw 35, operating through the bar and into an enlargement 36, secured to the guard-rail 6. This rail 6 is supported by means of an arm 38, suitably mounted on the bed. The heei during its passage along the table is subjected at all times to the pressure exerted by a retention-spring 39, assuming an edgewise position. and which has its one end secured to the guard-rail 4, as at 40, its free end and, in fact,the greater portion vof its length being located at a distance from the guard-rail in order to utilize the resiliency of the spring to its greatest extent. A bufferspring 4l, secured centrally of its ends, as at 42, bears against the one side of the spring in proximity to the free end thereof, thus effectually preventing undue movement of the spring without impairing its resiliency in the least. The heel after having the ends of the rand thereof severed continues in its course and comes into engagement With a spring-arm 43, the one end 44 of which is embedded within the guard-rail 7, the free end projecting at some distance from this rail. The counting or registering mechanism may Abe of any form, and I therefore do not limit myself in this particular, I having shown a peripherally-recessed dial-wheel, in which engages a pin or finger 45, carried by the free end of spring-arm 43, the outward movement of the arm caused by the passage of the heel causing the pin or finger to engage in one of the recesses and actuate the dial, thus presenting the succeeding recess of the dial to be similarly treated on the return of the arm.

We Will assume for the purpose of illustration that the severalparts have been arranged as previously described, and motion having been imparted to the drive-Wheel 20 the con- Veyer-chain is assuming its travel, at which time the operator, who has taken his position at the rear or flared end of the bed, places the heels with the projecting ends of the rands upon the table, with the ends of the rands extending through the space formed between the bed of the machine and the guard-rail and in engagement with the curved face of one of the conveyer-blocks. The heel will then be conveyed along the table until the foremost rand becomes engaged between the friction-Wheel and the rotary cutter, at which time the projecting end of the rand will be severed, the same procedure being practiced upon the rear rand. The heel then comes into engagement with the springarm 43, depressing the latter and causing the pin or finger to actuate the dial. The heel still being in engagement with the conveyer-bloclr will be conveyed to the end of the table, when upon the chain and block beginning their return movement the heel will by force of gravity become disengaged.

It will thus be seen that a continuous motion is retained at all times, and the operation of cutting and counting may be ceaselessly continued at the will of the operator.

As indicated at 50, the rail 7 carries a cutter-guard 50, which completely incloses the rotary cutter, preventing any accidental injury to the operator.

The bed is preferably provided with a very slight rise to the front of the cutter, as shown at 51, causing the lifts to ride upwardly and permit the rotary cutter to effect a cleaner cut.

I of course do not wish to limit myself to the precise construction shown and described, as it is obvious that various changes in the detaiis of construction and combination of parts may be resorted to without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a device of the type set forth, the combinationwith the table provided at its opposite sides with guide-rails and the conveyer, of a cutter journaled at one side of the said table,and means for pressingthe heels against the cutter, said means comprising a longitudinaliy-arranged spring secured at its one end to one of the said guide-rails.
